It establishes that these cascades share a common substrate: the digital layer through which failures cross sectoral boundaries. From these cases, it derives a ten-criterion evaluation grid to assess whether a given instrument (regulatory framework or exercise) takes cross-sector propagation as its object. https://nicolasroux.eu/blog/blog-european-digital-dependencies/ Tue, 31 Mar 2026 00:00:00 +0000 https://nicolasroux.eu/blog/blog-european-digital-dependencies/ Europe’s digital dependencies: what breaks first, and what to do about it In February 2025, the United States sanctioned officials of the International Criminal Court. Within hours, the Court lost access to its cloud services, email, payment systems and software licences. The infrastructure that failed that day is the same infrastructure European public administrations rely on daily. Three months later, the Court had migrated to European open-source products. That fact tends to surprise people more than the sanctions themselves. https://nicolasroux.eu/publications/european-digital-dependencies/ Sun, 01 Mar 2026 00:00:00 +0000 https://nicolasroux.eu/publications/european-digital-dependencies/ Abstract When the United States sanctioned officials at the International Criminal Court in 2025, access to cloud services, email, payment systems, and software licences was cut within hours. The infrastructure that failed them is the same infrastructure European public institutions run on every day. This report maps that exposure across eight technological layers, from identity management to artificial intelligence, and finds that for six of the eight, production-ready European alternatives exist today.
